The correct answer is B. Ethyl Alcohol.
Fermentation is a metabolic process that converts sugars into alcohol. The most common type of fermentation is alcoholic fermentation, which produces ethanol (ethyl alcohol) and carbon dioxide. Alcoholic fermentation is used to make alcoholic beverages, such as beer, wine, and cider. It is also used to produce biofuels, such as ethanol fuel.
The process of alcoholic fermentation begins with the breakdown of glucose into pyruvate. Pyruvate is then converted into acetaldehyde by the enzyme pyruvate decarboxylase. Acetaldehyde is then converted into ethanol by the enzyme alcohol dehydrogenase.
The overall reaction for alcoholic fermentation is as follows:
C6H12O6 + 2 NAD+ + 2 ADP + 2 Pi â 2 C2H5OH + 2 NADH + 2 ATP + 2 CO2
Methyl alcohol (CH3OH) is a colorless, flammable liquid that is used as a solvent and a fuel. It is also known as wood alcohol or methanol. Methyl alcohol is not produced during alcoholic fermentation.
Acetic acid (CH3COOH) is a colorless, sour-tasting liquid that is used as a food additive and a solvent. It is also known as vinegar. Acetic acid is not produced during alcoholic fermentation.
Ethylene (C2H4) is a colorless, flammable gas that is used as a ripening agent for fruits and vegetables. It is also used to produce polyethylene, a type of plastic. Ethylene is not produced during alcoholic fermentation.
